FISCAL
POLICY AND TAXATION
Fiscal
policy is the government's
program with respect to the
amount and composition of
(i)
expenditure:
the purchase of goods and
services, and spending in
the form of
subsidies,
interest
payments on debt, unemployment
benefit, pension and other
payments, (ii)
revenues,
i.e.
taxes and non-tax fees
(such as license fees etc.)
and (iii) public debt:
borrowing to cover
the
excess of expenditure over
revenues. Borrowing can be
done from three
sources:
domestic
banks and the general
public, the central bank
(e.g. State Bank of
Pakistan), and
foreign
creditors.
Budget
Deficit, Budget Surplus and
Balanced Budget:
If
i>ii: the government is
said to be running a fiscal or
budget deficit and so the
government
must
borrow (or raise debt) to
cover the deficit; if
i<ii: the government is
said to be running a
fiscal
or budget surplus and so the
government can pay-off or
reduce its debt; if i=ii:
the
government
is said to be running a balanced
budget and the government's
net debt may
remain
constant.
Fiscal
deficits and debt are
often reported as a ratio of GDP.
Although, there is no
theoretical
benchmark
for what constitutes a
sustainable fiscal deficit or
public debt ratio, the
Maastricht
criteria
(for countries in the
European Union) is an important
practical guide. It stipulates
that
fiscal
deficit to GDP should be
less than 3% while public
debt to GDP should be less
than
60%.
The
Concept of Taxation:
Taxes
are general purpose,
compulsory contributions by the
people to the public
treasury (or
national
exchequer) to meet the
expenditure needs of the
government. Without taxes,
the
government
would not be able to deliver
services like law and
order, public
administration,
national
defense, free or subsidized
health and education
etc.
Since
taxes interfere with the
market mechanism, they are
considered distortionary, and
as
such
there is a long-standing debate
over the desirability of
taxes. In a way, the stance
over
taxation
defines the economic "right"
and "left" in HICs. The
market-friendly right (like
the
Republicans
in the U.S. or the
Conservatives in the U.K.)
believe in reducing the size
of the
government
and its spending so that
most of the services in the
economy are provided by
the
private
sector. As such they can
argue for lowering taxes
(since government spending is
also
less)
which according to them
distort private sector
incentives (remember the
Monetarist
argument
for removing income taxes in
the context of unemployment). By
contrast, the
interventionist
left (like the Democrats in
the U.S. or the Labour in
the U.K.) consider that a
big
and
active government essential
for the delivery of better
public services and
therefore are
often
against cutting taxes and
transferring the responsibility of
providing these services to
the
private
sector.
The
Debate over
Taxation:
There
are two dimensions to the
debate over taxation:
equity
and efficiency.
The
Concept of Equity:
Equity
represents that principle of
taxation which emphasizes
fairness or just sacrifice,
i.e.
everyone
should pay tax according to
his/her ability. So if a person
earns higher income,
s/he
should
be subjected to a higher tax
rate. Thus, for e.g., a
person earning Rs. 2,000 a
month
should
sacrifice 10% of his/her
income as taxes (i.e.
Rs.200), whereas a person
earning Rs.
200,000
should sacrifice 60% of
his/her income as taxes
(i.e. Rs. 120,000). In the
absence of
such
progressive taxation, the
rich person would have
also paid a 10% income
tax rate (i.e.
Rs.
20,000). Progressive taxation, in
which the tax rate
increases as income increases, is
an
application
of the vertical equity
principle which espouses the
Robinhood approach of
taking
135
Introduction

VU
money
from the rich and
distributing it to the poor.
While controversial, the
vertical equity
principle
in taxation is applied in one
way or another in most
countries across the
world.
Horizontal
Equity:
A
less controversial principle
relates to horizontal equity
which says: identically
well-off people
should
be taxed identically, i.e. no
discrimination due to race,
gender, caste, religion etc.
There
are
many examples, however, of
violation of this principle
and often one comes
across an
individual
belonging to a certain community or
grouping enjoying certain
economic privileges
not
enjoyed by a similarly endowed
individual of another community or
grouping.
We
now turn to the efficiency
dimension, which concerns
the distortionary effects of
taxation,
esp.
the possible negative
effects on private sector
behaviour and incentives.
The more
distortionary
a tax, the higher the
efficiency concerns surrounding
it.
The
Concept of Efficiency:
To
illustrate the concept of
efficiency, it is useful to develop an
understanding of what is
meant
by
a Pareto-efficient allocation of economic
resources. This is a situation in
which it is
impossible
to move to another allocation
which would make some
people better off
and
nobody
worse off. In the context of
the production possibilities
frontier, therefore, points on
the
frontier
are all Pareto-efficient, as it is
not possible to move to
another point (i.e. produce
more
of
one good) without incurring
some opportunity cost (i.e.
sacrificing the production of
some
other
good).
Economists
argue that a free-market
perfect competitively economy
where P=MC
automatically
delivers the optimal
allocation in the economy
(Pareto-efficiency), so any
government
intervention (like tax) that
interferes with that
allocation generates
efficiency
losses.
The efficiency (or welfare)
loss of a tax can be
illustrated by a simple demand
supply
diagram.
It can be seen that the
loss in consumer and
producer surplus is greater
than the
revenue
gain to government.
Does
the above argument mean a
tax can never be justified
on efficiency grounds?
No.
There are two cases in
which imposing a tax may
actually be better than not
imposing it.
i.
When there are market
failures, and a tax is
imposed to bring the
marginal social
cost
equal to marginal social
benefit.
ii.
When there are existing
distortions in the economy
and taxes are imposed
to
spread
the distortion over many
commodities rather than
placing the burden on
just
one commodity. Another way
to say it is: it is better to
impose a small tax on
a
number of commodities to raise a
certain amount of government
revenue,
rather
than impose one large
tax on one or two
commodities only.
Types
of Taxes Which a Government
Can Impose:
With
the theory of taxation
covered, we can now move to
the actual menu of taxes
the
government
can impose to raise revenue
for itself.
i.
Direct taxes, like
income tax, which is imposed
on factor incomes. Income
tax for
individuals
is called personal income
tax, while for firms is
called corporate
income
tax.
ii.
Indirect taxes, like sales
tax or value added tax,
which is imposed on
expenditure
on
goods and services
iii.
Tariffs which and are
imposed on import
expenditure
iv.
Wealth or property taxes
which are imposed on fixed
assets.
For
LICs, income tax collection
is very low and indirect
taxes often account for
more than 2/3rd
of
total revenue as citizens
often under-report their
incomes in these countries,
there is no
voluntary
tax payment culture, and
income tax collection
agencies are weak and/or
corrupt. By
contrast,
for HICs, income taxes
are much more important,
accounting for over
2/3rd of total tax
revenue.
136
Introduction
to Economics ECO401
VU
Disposable
income is obtained by subtracting
income tax from total
income. At the
national
level,
disposable income Yd is
calculated as Y-T, or Y-tY, where t is
the net income tax
rate.
One
important question before
governments is determining the
optimal tax rate, t, for
the
average
citizen. If t is too low,
not enough taxes might be
collected to enable the
government
to
run and provide proper
services. If t becomes too
high, the incentive for
citizens to work will
be
reduced, meaning national
income will go down and
tax collection will fall.
Also at very high
levels
of t, the incentive to cheat
and evade taxes increases
and the government,
therefore,
might
face serious enforcement
problems.
The
Laffer curve:
The
relationship between tax
rate and tax revenue
collection can be summarized in
the Laffer
curve
diagram. In the tax
revenue-tax rate space, the
Laffer curve plots as an
"inverted U",
delivering
an optimal tax rate t* which
is less than 100%.
Expenditures
and the Effects of Fiscal
Policy:
Having
concluded the discussion on
tax policy and taxation,
let us now focus on
expenditures
and
the effects of fiscal policy
in aggregate.
Expenditures
may be categorized as recurrent
and development. The former
includes interest
payments
on debt, salaries and
administrative expenses of all
government ministries
and
departments,
and other exigent recurrent
charges on the exchequer.
The latter mainly
social
sector
capital expenditures, esp.
those which are expected to
yield long-term
development
benefits.
Examples are building a
school or hospital, laying
down a new railway
system,
building
a motorway etc.
Governments
often promise to undertake
heavy development and social
sector (i.e. health,
education
etc.) expenditures, but due
to scarcity of revenues and
borrowing possibilities,
can
only
manage small development
expenditures. A large part of
the budget in most countries
is
committed
to recurrent charges.
Repayment
of debt is reported below
the line with other
borrowing and debt
aggregates, as it
is
neither strictly recurrent
nor development
spending.
Revenues
(recurrent + development
expenditures) + interest payments on
debt] gives the
primary
surplus, i.e. the amount
available to service the
burden of public
debt.
The
tax-adjusted Multiplier and
the Balanced budget
Multiplier:
Taxes
act as a drag on the
multiplier effect of government
spending, since they
represent a
leakage
from the circular flow of
incomes. The tax-adjusted
multiplier k* is smaller than
the
basic
Keynesian multiplier, k, introduced
earlier. k* is given by
{1/[1-(MPC)(1-t)]}, where t is
net
income
tax rate, and T = tY. The
higher the tax rate,
the greater the leakage
and the smaller
the
fiscal policy
multiplier.
It
is interesting to consider the
special case of balance
budget multiplier. The
concept here is
that
if the government spends
Rs.10 bn and finances it by
increasing taxes by Rs. 10
bn, the
multiplier
will not be zero, as one
might initially expect. This
is because, the higher tax
causes
disposable
income to fall, which in
turn causes saving and
imports (the other two
types of
leakages)
to fall. Thus the net
leakage from the system is
less than Rs. 10 and
there is a
positive
multiplier effect, albeit
small.
Financing
of Deficit:
Since
the size of the balanced
budget multiplier is small, it is
not always possible to get
the
required
demand expansion by raising
expenditures and taxes
symmetrically. Thus, the
case
of
deficit spending and
financing must be considered.
Here the government spends
more than
its
revenues, and raises debt to
finance the excess of
expenditures over revenues.
The three
borrowing
options were mentioned
earlier:
i.
Borrow from domestic
banking system or general
public through a sale
of
treasury
bills and bonds. Bills
are short-term debt
instruments (< 1 year)
and
137
Introduction
to Economics ECO401
VU
bonds
are long-term bond
instruments (> 2 years).4 The
major disadvantage of
this
type of borrowing is that it
can lead to crowding out of
private sector
activity.
How?
Consider the market for
loan able funds. An
increased demand for funds
by
the
government will cause
interest rates in the
economy to rise (making
loans
more
expensive for everybody,
including the private
sector) as well squeeze
the
quantity
of credit available for
lending to the private
sector.
ii.
Borrow from the central
bank by ordering the latter
to print money and lend it
to
the
government (free or at an interest
cost) for onward spending.
All governments
would
love to do this, except that
this type of "apparently
free" financing is
highly
inflationary.
You can easily imagine why.
An increased supply of money
given a
fixed
supply of gods will
naturally cause prices of
those limited goods to
rise.
iii.
Borrow from foreign sources
either through bonds floated
on international capital
markets
or bilateral, multilateral or commercial
loans. The advantage of this
type
of
borrowing is that it does
not lead to crowding out
and is not
immediately
inflationary,
especially if some of the
loan helps finance import
expenditure. If all
the
borrowed money is spent
locally given a fixed
exchange rate, the
monetary
effects
of foreign borrowing might
become very similar to those
of borrowing from
the
central bank.
Should
the Fiscal Policy be Active
or Passive?
In
view of the above
complications, there is a long-standing
debate on whether fiscal
policy
should
be active or passive. Note
that in a Keynesian context,
even a passive fiscal stance
will
produce
an automatic stabilizer effect on
aggregate demand. How? If AD
falls, Y falls, tax
collection
falls, the net income
tax rate falls, which is
equivalent to a passive fiscal
policy
expansion.
Also, when AD and Y fall,
unemployment rises; which
means more people
become
eligible
for unemployment benefit,
which in turn causes
government expenditure to rise,
which
is
again equivalent to a passive
fiscal policy expansion. It is
easy to derive the
reverse
situation:
in which AD rises and fiscal
policy becomes passively
contractionary.
In
addition to the above, there
is an argument that active
fiscal policy cannot be
changed
without
a time lag. The government
passes its budget on an
annual basis, and thus a
mid-year
change
in AD which warrants a fiscal
policy response must wait
till the start of the
next fiscal
year.
Unfortunately, the demand
conditions might have
changed by that time!
1.
Other
arguments against active
fiscal policy-led demand-management
include the
effects
of a fiscal expansion on interest
rates and subsequently the
exchange rate. As
mentioned
in the discussion on BOPs, a
rising domestic interest
rate will cause
the
exchange
rate to appreciate in real
terms (due to the interest
parity condition).
This,
however,
will cause competitiveness to
decline will drive down
exports and lead to
BOPs
problems.
2.
Finally,
expansionary fiscal policies
can raise the national
debt (as you know,
national
debt
is simply an accumulation of past
fiscal deficits) which would
have to be paid off
by
future generations, possibly
through a painful increase in
their tax
contributions.
4
Bills
and bonds can be thought of
as certificates that the
government gives to its lenders in
exchange for cash.
The
terms on the certificate
stipulate when the
government will repay the
cash and what interest rate
it will pay till
maturity.
Thus if the government sells
you a 10% 10-year Wapda
bond worth Rs. 1000
today, it means you
will
give
the government Rs. 1000
today and receive the
Rs. 1000 from government
after a period of 10 years. In
the
meantime,
however, the government will
pay you interest at 10%
(or Rs. 100 per
year).

If
tax increases are `phased
in' as the economy recovers
from recession, how will
this
affect
the magnitude and timing of
the recovery?
It
would have a similar effect
to automatic fiscal stabilisers. It
would reduce the rate of
growth of
aggregate
demand and thus dampen
and slow down the
recovery. The hope of the
government
was
that this would make
the recovery more
sustainable and would create
confidence in the
financial
community that the budget
deficit would be significantly
reduced over the longer
term.
As
the budget deficit fell, so
the hope was that
this would allow interest
rates to fall. The
danger,
of
course, was that the
tax increases might totally
halt the fragile
recovery.
At
lot depended on confidence.
The more that investors
believed that the policy
would help to
make
the recovery more
sustainable, the more they
would invest and, therefore,
the more
sustained
the recovery would be. On
the other hand, if investors
believed that the tax
increases
would
kill off the recovery,
the less they would
invest, and therefore the
more likely the
recovery
would
peter out.
If
tax cuts are largely
saved, should an expansionary
fiscal policy be confined
to
increases
in government spending?
Ricardian
equivalence states that when
a governemnt cuts taxes (and
finances the
resulting
fiscal
deficit from borrowing),
taxpayers will not spend
the higher disposable
incomes they are
left
with as a result of the
lower taxes, because they
will expect government to
raise taxes in the
future
in order to pay the higher
interest cost of debt
incurred today. Under these
conditions,
increases
in government spending, provided
they are direct expenditure
on output-generating
activities,
will be more effective than
tax cuts in stimulating the
economy.
Could
you drive the car at a
steady speed if you knew
that all the hills
were the same
length
and height and if there
were a constant 30-second
delay on the
pedals?
Yes.
You would simply push on the
accelerator (or brake) 30
seconds before you wanted
the
effect
to occur. You would do this so
that the car would
end up braking as you went
down hill
and
accelerating as you went up
hill.
The
lesson for fiscal policy is
that if forecasting is correct, if
you know the precise
effects of any
fiscal
measures, and if there are
no random shocks, then
fiscal policy can stabilise
the economy.
How
can a government finance its
fiscal deficit?
By
borrowing locally (i.e.
issuing bonds), foreign
financing (including non-relpayable
grants) or
printing
money (i.e. borrowing from
the central bank). The
first of these methods is
least
inflationary
while the last one is
most inflationary.
Are
all taxes
distortionary?
A
naïve but not incorrect
answer is "Yes". Indeed all
taxes are distortionary,
"but", given existing
distortions,
imposing some taxes can
actually reduce the
distortion in the economy.
This is the
theory
of the second best.
Why
is the "without tax"
multiplier smaller than the
"with tax"
multiplier?
Because
taxes are a leakage from
the circular flow, and
the multiplier measures the
impact of an
injection
onto the circulr flow.
The more avenues for
leakages, the less will be
this impact.
How
is a sales tax different
from a graduated income
tax?
The
sales tax is a direct and
progresisve tax. It's direct
because it is a deduction from
the net
income
of an individual. It is progressive
because the graduated levy
ensures the burden of
tax
reduces
for poorer people (this is
consistent with the equity
principle that the tax
burden should
139
Introduction
to Economics ECO401
VU
be
commnsurate with "ability to
pay"). A sales tax is an
indirect tax because it
indirectly taxes
people's
incomes. What it taxes
directly is people's consumption
expenditure. Naturally,
the
sales
tax is regressive; a poor
person pays the same
percentage of the retail
price as tax as a
rich
person.
